The proposed research would leverage the University of Missouri and USDA HOLL plant material in the current USB backcrossing program as a foundation, as well as other unique University of Missouri and USDA HOLL and HOLL plus breeding lines and populations currently being developed, for incorporating the proposed plus traits through a similar parallel back crossing program utilizing molecular markers associated with the various plus traits. Breeding methods such as conventional forward crossing, early generation selection (pedigree), and utilizing large population sizes will also be used to maximize efficiency and probability of success in staking multiple composition traits into high yielding soybean varieties.
